Ismayıl Hakkı Baltacıoğlu, born in İstanbul in 1886, was a sophisticated person who had witnessed many important developments pertaining to the Ottoman State and Republic of Turkey before his death in 1978. After completing his secondary education at Fevziye Junior High School and Vefa High School, Mustafa Satı Bey, a famous pedagogist who became the principal of Darülmuallimin (Male Teacher's Institute) in 1909, sent him to Paris, London, Belgium, Switzerland and Germany to do research on pedagogy and handicrafts. Baltacıoğlu began teaching pedagogy in Darülfünun in 1913 and continued in this role until 1933. Baltacıoğlu became the first rector of Turkey in 1923, and is the foremost representative of the "Educational Reform Movement" in Turkey. He wrote prolifically on the disciplines of education, sociology, philosophy and religion. He also produced literary works such as stories, plays and novels.
